I thought I had a beautiful and early 31.6 syncros seat post (vertical lettering on the rear only), but it turns out its a 30.6. I've had frames with 30.9 and 31.6 posts but never 30.6, so my question is what frames had a 30.6 post size? Is it common or unusual? I've got nothing it will fit so intrigued by the size.
Real shame as its a lovely post.
